Etymology: Mustelus: Latin for weasel, an ancient name for sharks, possibly referring to the pointed snouts, swift movements and/or rapacious feeding behavior of smaller predatory sharks [strictly not tautonymous with Squalus mustelus Linnaeus 1758 since type was designated by the ICZN]. (See ETYFish); norrisi: In honor of American zoologist Harry Waldo Norris (1862-1946), Grinnell College (Iowa), who studied the cranial nerves of the Spiny Dogfish Squalus acanthias. (See ETYFish).
